Adverum Biotechnologies, Inc. is a clinical-stage gene therapy company targeting unmet medical needs in ocular and rare diseases. Adverum develops gene therapy product candidates intended to provide durable efficacy by inducing sustained expression of a therapeutic protein. The Company’s lead product candidate ADVM-022 is a single intravitreal (“IVT”) injection gene therapy designed to deliver long-term durability with robust treatment response, reduce the treatment burden of frequent anti-vascular endothelial growth factor (“anti-VEGF”) injections, and improve real-world vision outcomes for patients. ADVM-022 is targeting the treatment of patients with chronic retinal diseases that respond to standard-of-care anti-VEGF therapy, including wet age-related macular degeneration (“wet AMD”) and diabetic macular edema (“DME”). ADVM-022 utilizes a proprietary vector capsid, AAV.7m8, carrying an aflibercept coding sequence under the control of a proprietary expression cassette.
